Find the value of x and find whether the angles or supplementary or complementary.

Answer:
Both angles add up to 90° so they are complementary angles, x = 55
Step-by-step explanation:
=> We know that both angles add to 90°, so the equation will be;
(x - 20) + (x) = 90
=> Using algebra if solved all the way down, "x" will be 55.
